Question:
If A and B are two matrices such that A+B and AB are both defined, then
If A and B are two matrices such that A+B and AB are both defined, then
Updated On: Apr 23, 2024
- (A) A and B can be any matrices
- (B) A, B are square matrices not necessarily of the same order
- (C) A, B are square matrices of the same order
- (D) Number of columns of A = number of rows of B

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Explanation:
Addition is defined if order of A is equal to order of BA B nxm nxm is defined if m = n⇒ A, B are square matrices of same order
Addition is defined if order of A is equal to order of BA B nxm nxm is defined if m = n⇒ A, B are square matrices of same order
